' Patented July 18, "1911.

To all whom it may concern:

Be it known that I, WILLIAM W. DEAN,

' a citizen of the United States, residing at Si nal Devices; and I do hereby declare the f0 owing to bee full, clear, and exact description of the'i'nvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to warning signal devices and more particularly to such devices adapted to be used upon conveyances, such as automobiles, motor trucks, motor boats, etc., to give warning of the approach of the vehicle. I also contemplate other uses for my device which will be apparent to those skilled in the art. When used these devices are generally carried in exposed positions where moisture, dirt, dust and other foreign matter are apt to be caught and car of the chamber in which the device or a part thereof is mounted. It frequently happens that it is desired to mount the device in some certain position and when this is the case, it is highly desirable that the means provided for the escape of foreign matter should be adjustable so as to place it in a position most desirable for the escape of such foreign matter.

The main object of my invention is the provision of means for permitting the escape of this foreign matter and making the same adjustable, so that the opening or other means employed may be positioned as is most desirable. I prefer to perforate one of the walls of the chamber so as to provide a communication directly between the chamber and theoutside and then make this wall adjustable. In the form of my invention shown, I have thus modified the front wall of the chamber and have loosely secured it to the device by such means as canv be loosened, the front adjusted to the position desired and then tightened to firmly clamp the front to the device.

My invention will be best understood by reference to the following description when taken in connection with the accompanying illustration, showing one specific embodiment thereof, while its scope will be more particularly pointed out, in the appended claims.

Figure 1 shows a portion of an automobile with a warning signal device applied thereto. ing signal device to which my invention is applied; Fig. 3 is a front elevation of such device having a portion of the resonator cut away. Fig. 4 is a cross section of the device shown in Fig. 2. "Fig. 5 is a detail of a modification. Fig. 6 is a detail of a second modification. Fig. 7 is an enlarged detail of a )ortion' of the device shown in Fig. 4.

Re erring now. to the drawings, an automobile is shown at 1, upon which a warning signal device 2.is mounted. In the form shown, this device consists of a horn, preferably an electricall controlled horn. This horn is control ed by a switch 3 mounted upon the steering device 4.' The signaling device may consist of a frame part 5 which supports a vibratile member 6, preferably-.51., diaphragm which is adapted to produce a signal when actuated. Actuating means 7, preferably electromagnetic means is provided for operating this diaphragm. The magnets control an armature8 which serves the double purpose of actuating the member 6 and controlling a switch 9 in a circuit 10 of the signal device.-

11 is a casin part forming a wall of the chamber in w ich the mechanism of the signal device is housed. Another part 12 is shown which constitutes a frontwall. of said chamber. This portion hasan opening 13 in the front thereof, through which a.

resonator 14; communicates with the chamber 15 formed by .the said parts. The

resonator is preferably curved at the outer.

end to form a bell shaped mouth 16, thus making the elements of the resonator of moisture, dust, irt, and other foreign matter which enters the chamber through the opening 13. In the formof my invention shown, a perforation '20 is ormed, pref- Fig. 2 is a vcrosssection of a warnerably in the front wall 12 othe chamber 15. This should be near the periphery of the chamber. though it will be obvious that the 10o curved. Means are rovlded for the escape a As a rule, it is desirable that the opening should be at the lowermost part of the chamber and in order to make it possible to so place the opening when the signal device cry is' fastened to the car in any position, I have provided means for adjustably securing the part inwhich this opening is made to the device so that should it be, desired to place the signal device with the-arm 21 vertical, and the opening 20 adjacent the bottom of the "chamber the part in which this opening is made may be adjusted so that the opening will be in the said desired position.

In the form of my invention shown in Figs. 2, 3 and 4, the part 5 is provided with an annular channel 30 adjacent the periphof the front leaving an outside ridge 31. The edge of the diaphragm is fitted in this channel and the diaphragm secured to the signal device by a ring 32 which is itself, attached to the part 5 by screws 33. The ring. 32 is channeled at 34- uponits inside outer edge for the edge 35 of the pe riphery of the front piece 12 which is fitted therein and adjustably clamped by screws 40 or other clamping means to the signal device. As shown in Fig. 3, the edges of these screws fit over the-edge of the pe riphery of the part 12. As will be readily seen, these screws may be loosened, the part 12 adjustably secured to the signal device and the screws tightened firmly clamping the part 12 down. In the form shown in Fig. 5, the ridge 31 has been reduced and the part 32 extended.

In the form shown in Fig. 6, an annular member 50 is provided which is clamped down by screws 51, the inner edge of the member 50 overlaps the periphery of the front 12, clamping it to, the signal device.

It will be seen that the front 12 may be adjusted to position the perforation 20 at any point upon the periphery of a circle and when said opening is formed at a point near the edge of the chamber, the parts may be'adjustcd so that this opening will be at any point upon the periphery of the said chamber. It will also be obvious to those skilled in the art that numerous and extensive departures from the form and details of the apparatus here shown may be made without departing from the spirit of this invention, the same being herein shown solely for the purpose of clearly illustrating one specific embodiment thereof.
